Abstract: A filament-feeding apparatus for a wet freshly dyed yarn has a feed wheel centered on and rotatable about an axis and having a pair of side parts having generally circular peripheries lying in parallel spaced-apart planes perpendicular to this axis, and a plurality of angularly spaced center parts axially bridging the side parts and having outer edges axially aligned with the peripheries. The wheel is open and free of structure in zones radially inward of the peripheries and radially outward of secants extending between the outer edges. A flexible endless belt having a width equal at least to the axial spacing between the peripheries is held by a plurality of pulleys in a circular arc radially against these peripheries so that the belt forms upstream and downstream nips at the ends of the circular arc. A filament is fed under tension tangentially of the wheel to the upstream nip between the side parts of the wheel and is withdrawn under tension and tangentially of the wheel from the downstream nip between the side parts. The filament is thus stretched over the outer edges into a succession of straight-line secants along the engagement arc and only engages the belt at the outer edges along this arc.

Title: Photo-electrochemical solar cell system - has cooling device comprising thermo-syphon to remove electrolyte from cell and return it after cooling
Inventor: HODES GARY
IPC: H01M14/00
Filed: 1980-02-01
Abstract: The system comprises in combination a photoelectro-chemical cell (PEC) and a thermosyphon, resulting in an improved performance of the PEC and in an enhanced utilisation of solar energy, while certain undesired side-effects due to thermal heating in the PEC are eliminated. The thermosyphon is pref. constructed from suitable materials resistant to the corrosive effects of the electrolyte, even at elevated temperatures. The PEC itself can be positioned in a container of any suitable shape. It may be curved, which results in a concentration of the incident radiation; or it may be flat, in which case less electrolyte is required and the photoelectrode can be closer to the front of the cell. The cell is advantageously thermally insulated, and this applies also to the conduits to the heat exchanger. Heat losses are thus minimised. The removal of unwanted heat from the PEC increases effective cell life.
